[Genetic Polymorphisms of 26 Y-STR Loci in Fujian She Nationality and Its Forensic Application].

Objective To study the forensic application of Goldeneye TM DNA ID 26 Y Kit in the She nationality. Methods Through capillary electrophoresis, the genotype of 26 Y-STR loci were analyzed in53 unrelated male individuals from Fujian She nationality. The population genetics parameters such as allele frequency and haplotype diversity were calculated. The comparisons among the She nationality and the other nationalities were analyzed. Results A total of 126 alleles were observed on the 26 Y-STR loci of 53 unrelated male individuals. The allele frequencies and GD value ranged from 0.010 1 to 0.886 8and 0.211 2 to 0.846 2, respectively. The GD value was greater than 0.5 in the 19 loci. A total of 47 haplotypes were observed. Based on R ST, multidimensional scaling plot indicated that the genetic relationship among Fujian She nationality and Minnan Han nationality was closest, followed by Southern China Han nationality and Northern China nationality. Conclusion Goldeneye TM DNA ID 26 Y Kit including 26 YSTR loci has good polymorphism in the She nationality. As an additional system, it has forensic application value in some special cases.
